US Space Force EWS-G1 (formerly GOES-13) Infrared Window (10.7 µm) images (above) showed Cyclone Batsirai in the South Indian Ocean as it rapidly intensified from a Tropical Storm at 06 UTC to Category 2 storm (at 12 UTC on 27 January) and briefly exhibited a pinhole eye — and then rapidly collapsed back to Tropical Storm intensity by 00 UTC on 28 January 2022 (SATCON).
EWS-G1 Visible (0.63 µm) images (below) also displayed the rapid formation of a pinhole eye.

A map of Sea Surface Temperature from the CIMSS Tropical Cyclones site (below) showed that Batsirai had been moving over relatively warm water during its period of rapid intensification.
